UNITED STATES CHARLES CRETORS, OF CHICAGO, ILLINOIS.

ROASTING APPARATUS.

Application filed April 30, 1921.

To all whom it may concern Be it known that I, CHARLES CRETORS, acitizen of the United States of America and aresident of Chicago, in thecounty of (look. State of Illinois, have invented certain new and usefulImprovements in Roasting Apparatus, of which the following is aspecification.

This invention relates to that class of roasting apparatus for peanutsand the like, in which a horizontally arranged revoluble cylinder ordrum is provided with an axially arranged heating element for effectingthe roasting operation, and the present improvement has for its objectsTo provide a structural formation and association of parts in which arevoluble containing cylinder or drum is combined with an axiallyarranged and stationary electrical heating element, and by means ofwhich an even and uniform roasting operation is effected, with anavoidance of scorching of any portion of the material operated on, andwhich is adapted to provide a safe and sub stantial support andencasement for the electrical heating unit and its connections orconductors.

To provide means for a ready removal of a sample of the materialoperated on, for the purpose of testing and ascertaining from time totime the progress of the roasting operation, all as will hereinaftermore fully appear.

In the accompanying drawings:

Fig. 1, is an elevation showing the present improvement in position onthe rear of a vending stand for peanuts, etc.

Fig. 2, is an end elevation of the same with parts broken away and insection.

Fig. 3, is a detail central longitudinal sec tion of one end portion ofthe roasting apparatus.

Fig. 4, is a similar view of the other end of the apparatus.

Fig. 5, is a transverse section on line 5-5 Fig. 4.

Fig. 6, a detail transverse section on line 66, Fig. 3.

Like reference numerals indicate like parts in the different views.

Referring to the drawings, 1 designates extensions of the side Walls ofa peanut vending stand affording support for the parts and mechanisms ofthe roasting means, and to such end each extension is formed with acircular flange 2, on its inner face for the at- Serial No. 465,877.

tachment of the curved enclosing casing 3, and with a curved guidegroove for the move ment of the door 4 by means of which the entryopening in the casing 3 is closed. Each of the wall extensions 1, isalso formed with a circular openin in which an end of the hereinafterdescri ed roasting drum or cylinder is adapted to rotate.

5 designate bracket or bridge pieces secured to the respective wallextensions 1 and extending to the axis of the aforesaid circularopenings of Wall extensions 1 to provide support of the roastingcylinder or drum, and for the electrical heating unit hereinafterdescribed.

6 designate annular heads or rings forming fixtures on the inner ends ofthe bracket pieces 5 in concentric relation to the circular openings ofthe Wall extensions 1 aforesaid. Said rings 5 are formed with bearingsfor the carrying heads of the above mentioned roasting drum or cylinder,and with supports for the outer circular shell of the heating unit.

7 designates the revoluble roasting drum or cylinder, preferably of thedetail construction shown in Figs. 3, 4 and 5, and having a double wallwith an intermediate air space to retard outward radiation of heat. Thesaid drum 7 is formed with a longitudinal peripheral opening for fillingand emptying uses, and with a closure plate 8 for said opening of anyusual form and arrangement.

9 designate skeleton end heads or spiders secured to the respective endsof the drum 7 and provided with annular hubs for bearing on the annularbearing rings 6 above described.

10 designate transparent end walls fittin the ends of the drums 7adjacent to the end heads 9 for the purpose of visual inspection of thematerial undergoing the roasting op eration.

11 designate a series of deflecting vanes or blades fixed within thedrum 7 near the respective end thereof, and adapted to deflect thematerial towards the middle of the drum in the revolution of the same.

12 designates a supporting sleeve or shell extending between and fixedlysecured to the annular heads 6 aforesaid, to constitute an enclosure forthe hereinafter described heating unit and intermediate shell thereof.In the preferred construction the sleeve 12 is formed of perforate metaland having a main portion of woven Wire fabric or the like and alongitudinal crown strip 13 of imperforate metal, as shown moreparticularly in Figs. 3, and 5. With such construction the transverseHow of material which takes place in actual use, and due jointly the enddeflecting blades 11, thereof, is not impeded owing to the smoothsurface of the crown strip 13 aforesaid.

14ldesignates the electrical heating unit, which may be of any usual andsuitable construction, preferably however of the type formed by a seriesof spaced collars and central core as shown more particularly in Figs. 3and ,4. In the construction shown, the heating unit 1 1 is supported inplace by hanger brackets 15 on the end heads 6 aforesaid, and isconnected witha suitable source of electro-motive force by conductors 16and 17 that are housed in part in recesses or channels in the bracketpieces 5 as shown.

18 designates an intermediate shell arranged between the enclosing shell12 and the heating unit 1%. In the preferred construction shown theshell 18 is formed of perforate metal longitudinally corrugated toafford greater resistance to lateral fiexure, and with its borecommunicating with the bore of the annular heads 6 for the purposehereinafter stated.

19 designates an opening or passage formed in the periphery of the shell12 and shell 13 near one of the same, and 20 designates a hinged coverassociated with and controlling said opening.

I 21 designates a crank shaft attached to the cover 20 at its point ofpivotal attachment to the shell. 12, and extending out through anannular head 6 for convenient manual operation and so that by a movementby hand of said crank shaft in one direction, the cover 20 is moved awayfrom the opening 19 to permit a sample of the material operated onpassing into the end portion of the bore of the shell 12 and from thenceto pass to a hand of the operator along the fixed guide chute 22 formedas an extension of the adjacent annular head 6. By a movement of thecrank shaft 21 in the opposite direction, the cover 20 is caused toclose the opening 19 and prevent any such outflow of the material.

23 designates a shield piece associated with the annular head 6 nextadjacent to the aforesaid outlet opening 19, said shield piece is of asegmental form and is provided with an inturned bottom flange 24 asshown more particularly in Fig. 3, adapted to protect the adjacentelectrical conducting connection 1? and at the same time admit of thefree outflow of the material for inspection purposes.

25 designates a bevel gear wheel fixedly associated with a skeleton endhead 9 of the roaster drum 7, and enclosed and protected to therevolution of the drum 7 and from accidentalcontact by a flanged rim 26on the adjacent annular head 6 as shown.

27 designates a bevel pinion meshing with the bevel gear wheel 25 andcarried by a countershaft 28 journalled on the inner side of a bracketpiece 5 aforesaid.

29 designates an electric or like motor arranged above the enclosingcasing 3, above described, and preferably in a separate casing 30 asshown in Figs. 1 and 2. The motor 29 is adapted to supply driving powerto the other mechanisms of the vending machine in addition to operatingthe roast. ing drum 7, andto such end said motor has connections asfollows 31 designates an obliquely arranged shaft connected at one endto the power shaft of the motor 29 and having bevel gear connections 32at its other end with the countershaft 28 above described.

In the practical operation of the present improvement, the roasting drum7 is filled with material to be operated on, to a horizontal levelapproximately even with the crown 13 of the shell 12 which encloses theheating unit 14:. With a rotation of the drum 7 such horizontal level orsurface of the materialis moved to an inclined position until such aninclination is reached that the surface material will roll down in aconstant manner over the shell 12 and be exposed to a very effectiveroasting action from the centrally arranged heating unit 14 aforesaid.
